Before 2 days I've changed RAM voltage (I've increase it) from the BIOS and after i save the changes and exit my computer keeps restarting and I've black screen (even the BIOS Don't appear) and no Beebs ????
so please tell me what is the wrong thing in my Computer ????
Is it a custom built computer or a pre-packaged one? If it is pre-packaged, did you open it at all? From what you described, it sounds like you have some static electricity damage. Most likely to either your motherboard or RAM.
